In this manner the steel is held back against. the pressure ofthe drivers in such' manner as to keep the tachsliirmly in the required position until -the' saine have been partially driven. l f ro For the actuation of the drivers 35 they are attached to a vertically-movable har 36, having connected therewith guiderods 37 37, working in tubular guides 38 38 on the up right sides of the machine-frame, the said har i 5 86 having 'connected therewith connectingrods 39 39, formed with straps 391 391, itting the eccentrics 40 40 on the shaft In practice suitable provision will be made for supplying tacks and delivering thorn in zo succession to be driven; We have represented in the drawings' convenient arrangements for the purposecomprising principally hopoers 4l Lil, attached to the upper portions ot the side frames l l, chuies'eil 42, leading downz 5 wardfrointhe said vhoppers el al, and feedplates 43 413, working vertically within the said hoppers for the purpose of lifting tacks into position to pass onto the chutes 42 e2, the said feed-plates having their upper edges grooved 'to receive the tacksvaud also having the' said upper edges inclined, sothat the tacks may slide therefrom onto the upper ends of the chutes 42 42, the said feed-plates being connected, as at fle 44, with projections 35 depending from the bar 36, and. therebyviieing actuated as thesaid har rises and falls. A suitable arrangement et escapement de? vices for `causing the 'tacks to he delivered singly at the lower end of each chate/is represented in plan in Eig. ld, which shows portion of one chute and a nninher of tacks supported thereby. The escapenient'siides 45 i5 are representedl as operated in one direction by means of campieces 46 ad, attach ed 4to the har 3 5, and in the other directionby means oi springs i7 4:7, acting in opposition to the cam-pieces. i f

For the purpose ot introducing .the tacks properly into the holes o c of the steel i) a guide 49 (see more particularly Figs. 5, 7, 8, and' 9) is employed inconnection with each Each guide 49 is provided with a passage 50 therethrough, and in the normal position of the guide 49 the top of this guidepassage 50 is beneath the tube 4S in position to receive a tack as it drops point fora' most froml the said tuhe.l For the purpose of centering the tack, the guide 49 is furnished at the bottom of the passage 50 with two jaws 5l. 52. The jaw lisier-ined with a -shaped notchwiiich receives the jaw 52, the latter -loeing of al corresponding shape to enable it tit and Work within 't-hfenotch of the jaw 4The apex of the jaw die truncatedand .in dilerent steels.`

slightly concat/ed in order when the jaws are close ltogether` an opening may exist into which thepoint of afdescending tack. may enter. These jaws operate to place the 7o point of the tack in line with the tack-hole c in the steel b, so as to insure the entrance of the said point intothe said tack-hole at the proper time. y The holes which are formed in the ends of 75 thesteels for the reception of the tacks vary in position in dilerent'steels more or lessiu practicefthat is to say, the' said holes are located at the middle :of the width of the steel; but .their-positions in the lengths of diierent steels vary. `In order, therefore, to enable the tack to End the tack-holes c c, the guides i949 are given amovemcnt lengthwise of the'steel b, this movement bengsuft cien-t in extent to take care of thelwidest 85 v range of variation in the position of the holes As the guides .move lengthwise oi` the steel after receiving tacks they carry such tacks to the holes in the steel, and as soon as the tacks arrive over the saidholes they drop into the latter. For the actuation of the guides 49 49 they are connected with the slides 53 53, the latter lwerking in guideways .at 54 5e and being here represented as connected by means of rods 55 55 with levers 56 56, operated in one direction oy means of side cams 57 57 on the shaft 3 and in the other direction by means of springs 58, one of which is represented in Fig. 2. In order to euahlethe guides to conform to any curvature of the steel, they are loosely or pivi otaily connected, 'as at 59, with the 'slides 53.

l(Sec Figs. 7, 8, andi) more especially.) In

order to insure the entrance of the point of a. tack into the tack-hole in steel when said point reaches the said tack-hole in the movement of the guide i9 the passage 50 throu h/thesaid guide sl'ants downward and in thi? irection in which the guide moves iucarryingy the `tack to the tack-hole. In. the present IIO case such movement is inward from the end of the steel toward the middle of the length thereof, and consequentlythe passage 50 inclines downward and inward. Atack occupying the said passage 50 incliues poiutfore- :f5 most-th at is to say, the point 'thereof inclines forward toward the hole in the steel. When in the inward inoveunenI of the guide the point of the tack enters fhe .hole in the ste'el,v the continued movement f the guide operates with a tendency to cause the tack to stand, upright in the said'1 hole, thus facilitating greatly the readiness with which the tack'willI enter or drop into the sal*l hole. If the asf" sage 50 iu the'guide were vertical', the ric- "z5 tion of the point of the tackin sliding alongthe uppersurface of the steel would tend. to y cause the tack to incline reversely,and in4 consequence the tack would be likelyy to bin over the edge offthe. tack-hle in `the stee 13o 51 52ers separated at the ,beginning of the inward movement of the guide 49. To this end the jaw l is made movable relatively to the guide a9 and the other jaw 52, and at the beginning of the said inward movement of the guide it is separated from the jaw 52 by a quick movement. Herein the movable jaw 5l is shown provided on the recurved inner end of a strip 511, surmounting the guide 49 and formed with an opening 512 therethrough, which last in the closed position of the jaws registers with the passage 50 in the guide, so that a tach in descending from the tube 8 passes through the saidopeniug 512 on its Way to the passage 50 oli" the guide. Strip ill is connected by link 60 with a lever G1, mounted on a fixed pivot at G2 and loosely connected with. ,the slide by means oi a pin or screw G3, projecting from. the said slide and Working in a longitudinal slot that is formed in the said lever (il. By moans of the l said screw or pin, the lever, and the link the movement ofthe slide 53 is transmitted in accelerated ratio to the strip 511. This takes the movable jaw away from the tach, the lata ter, however being held bach against the concave end of the jaw 52 in consequence of the friction of the point of the tack against the upper surface of the steel b. The jaw 52 is movably connected with the guide 49, being arranged to slide upon the hitter and being backed up by e. light spring 6l to hold the said jaw in Yits normal position. .The said jaw is capable of yielding upon the application of slight force thereto, and in operation noon as the tact; enters the tack-hole the resistance which the tack offers against the continued movement of the jaw 52 with the guide 49 serves to arrest further advance of the jaw 52.

Each body-blank o. in turn as it is pushed forward by the feed-bars 9 9 pushes ahead of it the shank-stiileuer which/has been completed by the attachment of the steel thereto.` The nished shank-stiffeners drop oft the edge of the bed or table 2 onto e. traveling belt or conveyor-apron 65, which is shown in part in Figs. l and 2, but omitted from Fig. 3 for the sake Voi clearness, the said apron passing around a. roll 66 on a shaft G7, which is driven by a band 68 from the main shaft 3. While on the belt or conveyenapron the shank-stiieners may be inspected and the defective ones removed.
